Yeh, from perspective "Fitor" and "Screwhead" make the most sense. "Cy-Kill" and "Tank" have a fair place in a first wave for being the first two figures; "Leader-1" and "Turbo" shows that someone there's watched Gobots.

From the whole Machine Robo range Leader-1 is really an astonishingly bad choice for Guardian leader in terms of design, quality, etc. Turbo really would have been a much better choice. Not that giving the guy a special skill of a forcefield he could hide behind gave him much of a chance.
